7 Claims. (Cl. zip-124) In ,machines in which fabric is formed from or incorporates yarns or threads running lengthwise of the fabric, such yarns or threads are commonly supplied from long rotating shafts or beams extending substantially the full width of the machine. Commonly such yarns or threads are furnished on large spools which are mounted on the beam. For brevity, I shall refer hereinafter only to warn intending to include in that term the various kinds of filaments that may be formed into or incorporated in fabrics.

The necessary restraint on the unwinding of the spools or the forcible driving of the spools to unwind the thread is applied through the beams. When the machine is quite wide, two ormore beams are aligned and coupled together in such a way that the restraint on or driving of the beams is applied at the end of the series and transmitted from one beam to another.

My invention provides an improved form of mounting for yarn beams peculiarly well meeting the conditions.

Y In the accompanying drawings which illustrate 1' the form of my invention which I now prefer,

as applied to two yarn beams disposed end to end, both driven and braked at one end of the machine: Fig. 1 is a plan view of the yarn beams with their spools and associated mechanism. Fig. 2 is a sectional plan view at the driving and braking end of the apparatus. Fig. 3 is a vertical section of the mechanism adjacent the brake substantially on the line III-Ill of Fig. 2. Fig. 4

is a sectional view showing the interconnection and mounting of the adjacent ends of the two yarn beams. Fig. 5 is a perspective view of the interconnecting device that I use at the end of each yarn beam that is adjacent another. Fig. 6 is a sectional elevation at the opposite end of the beam structure. Fig. 7 is a plan view of the latter, drawn to a larger scale than Fig. l.

The yarn beams are carried by three arms I, 2 and 48 of the machine in the present instance and can be assumed to be driven by a shaft 3 carried in one of these arms and furnished with driving power from a spur gear 4. The manner in which the beams are driven is immaterial. Likewise the form of the yarn beams themselves is immaterial for the most part. In the present instance, each of the yarn beams 5 and 6 comprises a tube provided with a cylindrical connection member I at one end and a connection 8 at its opposite end for support and interconnection with an adjacent beam and which preferably is of the form i lustrated; in case three or more beams are used in line, each intermediate beam may have a connection 8 at each end of it. customarily also, each beam is provided with a longitudinal key 9 and each spool I0 is provided with a corresponding key wayso that the spools are forced to turn with the beams. Preferably the spools are held tightly to each beam by providing one end of the beam with o.

fixed abutment l4 and the other end of the beam with a threaded nut l5 so that by turning up the nut I5 tightly the line of spools is clamped between this nut and the fixed abutment, It.

At the nondrivz'ng end of the beam line, the first beam 6 may be supported rather simply on a cylindrical bar l6 projecting from the frame member 2 and fitted to enter the hollow cylindrical member I of the beam. The beam (specifically, the member rotates on the bar Hi, and provision may be made for lubricating the en- .gaged surfaces as indicated by the lubricant passage shown. In order to allow this beam to be removed for replacement of its spools, I usually give the cylindrical bar [5 a sliding fit in machine arm 2 and provide it with some form of lock H to prevent it from being slipped out of supporting position inadvertently; conveniently such a" lock can consist of a body portion, as illustrated, provided with an eccentrically set pin l8 adapted to be turned by hand in a transverse hole in the bar 86; by turning this member in one direc tion its body can be forced against the machine arm 2 to lock the bar E6 in place, as illustrated, while turning it away from this position releases the member ll so that it may be lifted out of the hole in the bar and thereby the bar I6 released for endwise manual movement. Customariiy I also provide a set bolt l9 engaging with a flattened surface on the bar l6 to prevent the latter rotating, as will be understood from the drawings. While this bar construction lBis one which I prefer, it is also representative of supporting means for this end of the beam structure which releases the beam 8 for endwise movement when taking this beam from the machine.

At the opposite end of the beam set, I prefer- 58 the end I to be released readily by simply taking out the bolts 24 and lifting off the cooperating cap piece 23. The saddle member 22 is driven by the flexible coupling and for this purpose I provide the driving or controlling shaft 3 with a sleeve 25 keyedhtoit and provided with a few radially-extending portions 26 adapted to receive bolts 26a. The saddle 22 I then mount on the sleeve 25, but free to rotate thereon, and this circular portion 21 of the saddle member 22 I also provide with spaced axially-extending bolts 21a located intermediate the driving bolts 26a.

A ring 28 of rubber, leather or other material suitable for flexible couplings joins the bolts 26a and 21a, i. a. this ring is pierced by all of these bolts The operative utility of the flexible coupling thus provided will be understood by those skilled in the industry.

When it is desired to apply a brake to the beam or beams, this is done readily by providing the radially-extending portions 26 with an encircling brake drum 3| and outside this a pair of brake shoes 32 hinged to the frame member I at 33 and at their opposite ends connected by a bolt and adjustable spring as indicated at 34, as will be understood from the drawing and prior practices.

As before indicated, the beams and 6 are connected so that the beam 5 drives the beam 6. For this purpose and also to support these two ends of the beams 5 and 6, I preferably provide connections suchas 8, as before indicated. Each of these connections comprises a body portion 40 which is fastened to the end of the respective beam in some suitable manner, e. g. internally by a cross bolt 4i as illustrated, and a projecting tongue 42 located in part at least entirely at one side of the axis of the beam. The outer surface 43 of each tongue 42 is formed on radii having the axis of the beam extended as their center; i. e. the surface 43 comprises a part of a cylinder, as it were, the axis of which is the prolongation of the axis of the beam. The opposite surface 44 is usually a plane surface and usually I locate its root 45 along a diameter of the yarn beam, although on occasion it may be located at one side of a diameter. From this root 45, the plane surface 44 inclines outwardly toward the opposite cylindrical surface 43 so that the tongue 42 is thicker at its end 46 than at its outer end. When two beams 5 and 6, each provided with such a connection 8', are brought together with the plane surfaces 44 engaging each other. obviously one may drive the other; The outer surface 43 is made of such size that when two tongues 42 are thus brought together these outer surfaces 43 expand as one tongue is run up on the other (see Fig. 4) until they fit a bearing, for example, a ball bearing 4'! provided on an arm 48 of the machine to support the two adjacent ends of the two yarn beams. Each yarn beam may be taken away easily by simply withdrawing it from the bearing and likewise may be again replaced in position easily, the two beams simply being thrust together sufiiciently far for their tongues 42 to seat within the bearing 4'! provided for them. The tongues 42 are of such length that they engage and fill the bearing 4! radially before the end of either tongue 42 strikes the body portion 4|! of the opposite connection 8, as will be observed at 49 in Fig. 4.

It will be understood of course that the details of construction and operation described above and illustrated in the drawing are subject to considerable modification and variation in form and accordingly that my invention is not limited to such details of construction and operation except as appears hereafter in the claims.

I claim:

1. A flexible operations-control for a yarn beam comprising a member rotatable around the beam axisand subject to the desired control, a second member rotatable about the beam axis and fixed to the beam, a ring of flexible material around the axis of the beam, and means at spaced points afiixing said ring to both said members.

2. The combination with a yarn beam, of means to detachably support one end of the beam, a saddle rotatable around the beam axis to receive and support the opposite end of the beam, a cap detachably fastened to said saddle to retain the respective end of the beam in the saddle, and means to effect the rotation of the beam connected to said saddle.

3. The subject matter of claim 2, characterized by the fact that said means to support one end of the yarn beam comprises a hollow member and a journal member, one at said beam and the other carried in a relatively fixed position, separable one from the other on the removal of the opposite end of the beam from said saddle.

4. The combination with two aligned yarn beams, of means at one end of one of said beams to support and affect the rotation thereof, a projection from the opposite end of said one beam, a projection from the adjacent end of the second yarn beam to cooperate with said projection from the first beam to affect the rotation of the second beam, a bearing to support said adjacent ends of the two beams, and means to support the opposite end of the second beam.

5. The subject matter of claim 4, characterized by the fact that said projections have mutually engageable plane faces, engageable by substantially endwise movements of the beams placing the two projections in said bearing.

6. Interengaging coupling and supporting means for adjacent ends of two yarn beams comprising a projection from the end of each beam located at one side of the beam axis and having a plane surface at its side adjacent its axis, said plane surface inclining away from the axis toward the free end of the projection, and having at its opposite side a cylindrical surface, and a hollow bearing to receive said two projections with their two plane faces in engagement with each other, said bearing engaging the projections at their cylindrical surfaces.

7. The subject matter of claim 4, characterized by the fact that said means to support the opposite end of the second beam comprises a member to engage said end of the second beam, said memberbeing removable from said second beam end to permit the second beam to be displaced longitudinally of itself.
